How to Integrate AGVs & AMRs with Existing Conveyor Systems

As warehouses and distribution centers across the Benelux strive for higher throughput and greater flexibility, many are looking beyond their fixed conveyor systems. The challenge is clear: conveyors are champions of high-speed, point-to-point transport, but lack adaptability. The solution? Integrating the dynamic, intelligent movement of Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs). This hybrid approach combines the best of both worlds, creating a robust, adaptable, and scalable material handling ecosystem. This guide provides a practical, step-by-step approach to achieving this powerful synergy.

Definition

Integrating AGVs and AMRs with conveyor systems is the process of creating a seamless material flow between fixed, high-throughput transport lines and flexible, mobile robots. This involves establishing physical handover points (e.g., a conveyor top on an AGV) and a digital connection, typically managed by a Warehouse Control System (WCS) or Warehouse Execution System (WES), to orchestrate tasks and ensure fluid, uninterrupted transport of goods.

Step 1: Analysis & Process Mapping

Before any hardware is purchased, a deep dive into your current operations is critical. The goal is to identify the "why" behind the integration. Where are the bottlenecks? Where does the rigidity of your conveyor system hinder efficiency? Common areas include:

• End-of-Line Transport: Moving finished pallets from a production line wrapper to a staging or storage area.
• Goods-to-Person (GTP) Interfacing: AMRs bringing totes or shelves to a picking station that is fed or cleared by a conveyor.
• Cross-Docking & Sorting: Using mobile robots to provide flexible connections between inbound and outbound conveyor lines, bypassing fixed sorters for specific tasks.

Map your material flows, quantifying a "day in the life" of your facility. Note volumes, peak times, and distances. In the Netherlands and Belgium, where logistics real estate is at a premium and labor costs are high (€35-€45/hour all-in for a warehouse operator), the business case often centers on freeing up staff from repetitive "human conveyor" tasks. Quantify this potential saving. For instance, if an operator spends 3 hours per shift moving pallets over 100 meters, an AGV can directly replace that, offering an ROI within 18-24 months.

Step 2: Choosing the Right Mobile Robot

Not all mobile robots are created equal. The choice between an AGV and an AMR is fundamental and depends entirely on your process. This is a crucial decision point discussed in our AGV vs. AMR guide.

AGV vs. AMR for Conveyor Integration

The primary distinction lies in navigation and flexibility. AGVs are the reliable workhorses, following predefined paths (magnetic tape, QR codes, laser triangulation). AMRs are the smart, flexible explorers, using technologies like SLAM to navigate dynamically, much like a car with GPS. For conveyor integration, this has specific consequences:

The Physical Handshake

The robot must physically interact with your conveyor. This is often achieved with a "conveyor top" module on the mobile robot itself. For a standard 900mm wide roller conveyor, the AGV would be equipped with a matching roller or chain conveyor segment. When the AGV docks, it raises its module to the same height (e.g., 500mm), and the PLC/WCS signals the transfer.

Step 3: Software & Systems Integration (The Brains)

This is where the magic, and the complexity, lies. Your existing conveyors are likely controlled by a PLC (Programmable Logic Controller). Your new robot fleet has its own Fleet Management System (FMS). Your warehouse has a Warehouse Management System (WMS). These three systems must communicate seamlessly. This is the role of a Warehouse Execution System (WES).

The Role of the WES

Think of the WES as the air traffic controller for your warehouse. The WMS knows *what* needs to be done (e.g., "move pallet 123 from A to B"), but the WES knows *how* to do it most efficiently.

1. The WMS sends a task to the WES: "Move pallet 123 from conveyor outfeed #4 to shipping door #9."
2. The WES checks the status of conveyor #4 via the PLC. Is the pallet ready?
3. The WES analyzes the availability and position of all mobile robots via the FMS. It assigns the nearest available robot.
4. The WES commands the conveyor to transfer the pallet onto the robot.
5. The WES tells the FMS to direct the robot to shipping door #9.

Without a WCS or WES, you are left with a "islands of automation" problem, where operators have to manually bridge the gap between the systems. As many Benelux companies have discovered, processes don't always scale as the business grows. Investing in a robust software layer is crucial for future-proofing your operations, a topic we've explored in-depth on our blog: Why Growing Companies Struggle with Scalable Processes.

Step 4: Implementation, Testing & Go-Live

Integration is a project, not a product. It requires a structured approach.

The Pilot Phase

Don't try to automate everything at once. Select one specific process flow for a pilot project. For example, the transfer from a single packaging line to a stretch wrapper. This allows you to test the technology, validate your ROI calculations, and get your team comfortable with the new "colleagues". A typical pilot might involve 1-2 robots and a single conveyor handover point, running for 4-6 weeks.

Safety First

In a mixed environment where people and robots work alongside fixed machinery, safety is paramount. The system must adhere to European standards (e.g., ISO 3691-4). This includes ensuring clear floor markings, safety scanners on the robots, and emergency stop protocols that can halt both the robot and the relevant conveyor section instantly. The handover zone is a critical safety area that must be designed to prevent any human access during the transfer process.

Training and Change Management

Your team is a key part of the integration. They need to understand how the system works, how to interact with it safely, and what to do when exceptions occur. Clear communication, hands-on training, and highlighting how the technology frees them up for more value-added tasks are key to a smooth transition.
